LIFTING-JACK.

Specification of Letters Patent. f Patented F910;), 1920.,

Application filed April 26, 1 919. Serial'No. 292,892.

To all whom it may concern;

Be it knownthat we, LLOYD C. CRIPPEN and CHRISTIAN H. SOHLINKMEIER,citizens of the United States, residing at Parsons and Walnut, in thecounties of Labette and Crawford and State of Kansas, have inventedcertain new and useful Improvements in Lifting-Jacks, of which thefollowing isa specification.

The invention provides a jack designed chiefly for use in connectionwith vehicles for lifting the wheels from the ground to admit of removalof the wheel for lubricating or other purpose or to admit of repairingor replacing a tire.

The invention provides a Vehicle jack which is quick acting and whichmay be reduced to compact form for convenience of carrying on thevehicle so as not to be in the way or occupy valuable space:

The drawing illustrates a preferred embodiment of the invention.However, it is to be understood that in adapting the same to meetdifferent conditions, various changes in the form, proportion, and minordetails of construction may be resorted to without departing from thenature of the invention as claimed hereinafter.

Referring to the drawing,

Figure l is a side view of a vehiclejack embodyingthe invention as itappears when in service.

Fig. 2 is a top view.

Fig. 3 is a front view.

Fig. 4 is a detail view showing more clearly the manner of connectingtheseveral parts. Y

Corresponding and likeparts are referred to in the following-descriptionand indicated in the several views of the drawing by like referencecharacters.

The jack comprises essentially three parts, a standard A, a lifting beamB and an opcrating lever C. The standard A is approximately of A shapeand consists of a single bar of metal bent into the form substantially,as indicated in Fig. 3. A cross bar a; connects the side members of thestandard near their lower ends and besides form-.

engage the inner faces of the side members of the standard to which theyare secured by rivets or other suitable fastenlng means.

The operating lever C is mounted upon a pin land this pin also serves asmeans for connecting the upper ends of the side members of the'standardA. i The shortarm of the lever C'is' provided with an open slot or notch'2 which is adapted to'receive a pin 3 at the movable end of the liftingbeam B. The long arm of the lever C is of a length so that its lower endwill engage the cross bar a and thereby limit the movement of theleverwhen its long-arm is swung downward into the plane of the standardwhen the latter is in upright position. I 1 V The lifting beam Bcomprises two sec tions 4 and 5 which are pivotally connected at 6,whereby to admit of the sections folding one upon the other to reducethe length of the beam. The section 4 consists of a single bar whereasthe section 5 comprises companion bars which are spaced apart a distanceto receive the section Land the, end

of the lever C. This is indicated most' clearly in Fig. 2,. When thesections 4: and o are extended and aline they are retained in theposltion indicated by means of the pin 6 andan element 7, the latterconsisting of a metal strap extending over the upperedges of thecompanion bar and having their end portions bent to engage the outerfaces of the bars to which they are attached by suitable fasteningmeans. When the section 4 is extended it engages the part of the strapextendingacross the space formed between the companion bars Comprisingthe section 5. When the lifting beam is reduced in length the section 4is folded so as tooccupy the space formed betweenthe corhpahion barsconstituting the section 5. .The.

pin ,3 connecting the opposite ends of the companion bars, receives thenotch or slot ted end of the lever G. A plurality of stops r cratinglever C and the section 4 is fold-- ed between the companion bars of theI section The lever C' is folded to 00- cupy a position in the plane ofthe standard. The folded lifting beam may be placed against thestandard, thereby occupying a small space. When the jack is set up foruse the section 4 is extended and the lever 'C is adjusted to receivethe pin or like faswith the ground or other surface.

tening 3 in the notch or slot 2. The standard is placed in uprightposition and the which the long arm of the lever C is swung downwardlyagalnst the cross bar a with the result that the upper portion of thelift ing beam is elevated and lifts the part resting thereon. V

The foregoing description and thedrawing have reference to what may beconsidered the preferred, or approved form of our invention. It is to beunderstood that we may make such changes in construction and arrangementand combination of parts, materials, dimensions, et cetera, as may proveexpedient and fall within the scope of the appended claim.

Having thus fully described our inven otion, what we clalm as new anddesire to selifting beam comprising two sections, one

of the sections comprising spaced companion bars, a fastening connectingthe bars at one end and adapted -toienter the notch or open slot of theoperating lever, a connecting element joining the opposite ends of thebars and a fastening pivotally connecting the other section with thebars of the first mentioned section, the parts being adapted to foldinto compact form. In testimony whereof we affix our signatures inpresence of two witnesses.
